Abstract

The invention discloses a solar energy Stirling engine device, comprising a cylinder with a hot cavity and a cold cavity, wherein the hot cavity is a solar collecting vacuum tube, or is communicated with the solar energy collecting vacuum tube to absorb solar energy to heat the working medium by the solar collecting vacuum tube. The solar energy Stirling engine device utilizes renewable solar energy as the energy source of the engine, does not have waste gas emission and is environmentally friendly; the solar energy collecting vacuum tube is used as the hot cavity and a hot source acquiring device simultaneously, thus simplifying the device and being convenient to control; the invention is applied in solar energy generation; the solar energy Stirling engine device greatly reduces generation cost, provides hot water when the engine works, and has simple equipment and high solar energy utilization ratio.

Description

technical field [0001] The invention belongs to the field of development and utilization of new energy, in particular to a Stirling engine device utilizing solar energy. Background technique [0002] Various engine installations are known in the past, generally internal combustion engine installations utilizing petrol, diesel or natural gas as fuel. Different from the above-mentioned engine equipment, the Stirling engine belongs to the external combustion engine equipment, which has low noise during operation and can work quietly. The basic principle of the Stirling engine is to heat or cool the working medium (generally gas) sealed in the cylinder to generate pressure fluctuations and vertical motion of the piston, and then convert the vertical motion of the piston into rotational motion to achieve An engine device. The closed cylinder of the Stirling engine is filled with a certain volume of working fluid. One end of the cylinder is a hot chamber and the other end is a ...
